If you wanna make one, it's a Webley and Scott flare gun with a camera flash in the barrel and a scope on it. Look for a cast of the Webley, there's a few floating around somewhere. I hope there's still one avaliable, though. Someone might pop around and give you more info. Mine's not the best. I know, I shouldn't rely on second-hand recon. I hope I was of some help, though.
